Enable Mapping to \\Hostname\C$ Share on Windows 7 or Vista

By | 24 May, 2014

The reason this doesn’t work is because of UAC (User Account Control). By default Vista doesn’t allow UAC elevation over the network with a local user account.

There’s a registry key that we can use to change this behaviour.

Manual Registry Hack

Open regedit.exe then navigate down to the following key.


If it doesn’t exist add a new 32-bit DWORD value named LocalAccountTokenFilterPolicy and set the value to 1.

At this point you can map to the C$ share and also perform some other administrative tasks remotely.
